Configuring the Trusted Network
User Guide 49
Changing the IP address of the trusted network
Sometimes it is necessary to change the trusted network address
range. For example, if you are connect two or more Firebox devices
in a virtual private network, each Firebox must use a different net-
work address range. For more information, see “What You Need to
Create a VPN” on page 93.
To change the IP address of the trusted network:
1 Type the IP address of the trusted network in your browser
window to connect to the System Status page of the Firebox X
Edge.
The default IP address is: https://192.168.111.1
2 From the navigation bar at left, select Network => Trusted.
The Trusted Network Configuration page appears.
3 Enter the first address in the new network address range in the
IP address text field.
The default subnet mask works for most networks..
Configuring the Firebox as a DHCP server
The DHCP Server option sets the Firebox X Edge to assign IP
addresses to the computers on the trusted network. The Firebox uses
DHCP to make the assignments. When the Firebox receives a request
from a new computer on the trusted network, the Firebox assigns
the computer an IP address. By default, the Firebox DHCP server is
enabled.
